Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In the description below, details such as system structures, interfaces, and technologies are provided as illustrations for thorough understanding of embodiments of the present disclosure, but not to limit the scope of the disclosure those specific embodiments. Also, a person with an ordinary skill in the art will understand that embodiments of the present disclosure can be implemented even without details that are omitted in the description below. Furthermore, detailed descriptions about well-known systems, devices, circuits, and methods are omitted so as not to hinder describing various embodiments of the present disclosure.

FIG. 1 is a network architecture diagram illustrating an exemplary system 100 for controlling mobile terminal access to third-party resources, according to embodiments of the present disclosure. For convenience, only components needed to describe embodiments of the present disclosure are shown. System 100 includes a mobile terminal 101, a first-party server 102, and a third-party server 103. In some embodiments, system 100 may also include a second-party server 104.

Mobile terminal 101, first-party server 102, third-party server 103, and second-party server 104 connect and communicate with each other, over a data network. A data network disclosed in this disclosure may include Local Area Networks (LANs) and/or Wide Area Networks (WANs), and may be wireless, wired, or a combination thereof. Mobile terminal 101 may be any terminal device, for example, a personal digital assistant (PDA), a cell phone or smartphone, a laptop, a tablet PC, or any electronic device capable of accessing data via a data network.

First-party server 102, third-party server 103, and second-party server 104 each may be a standalone server, or a server comprising several functional servers. A server disclosed herein can be a web server, an enterprise server, or any other type of computer servers. It can be a PDA, a cell phone or smartphone, a laptop, a desktop, a tablet computer, or any device that can provide data resources. The server may include software applications for providing data resources over a data network.

In some embodiments, a user of mobile terminal 101, through a client-side application associated with an account system, logs onto a first-party server 102 that corresponds to the client terminal. Afterwards, according to the user's operation command, mobile terminal 101 acquires, from first-party server 102, authorization information using which the user has logged in first-party server 102 and can be used for authorizing the user to log in third-party server 103. Mobile terminal 101 then transmits to third-party server 103 a login request message that carries the authorization information. After receiving the login request message, third-party server 103 verifies the authorization information included in the login request message. After having passed the verification, third-party server 103 authorizes the user of mobile terminal 101 to login using a login name of an account system. The login name is included in or corresponds to the authorization information.

In some embodiments, the authorization information can include, but is not limited to, an application identifier (e.g. “AppID”), a scope of authorization (e.g. what operations the user can do after logging in to the third-party server), uniform resource locator for redirecting a webpage (i.e., “redirect_URL”), and other information.

In some exemplary embodiments, the client-side application associated with the account system may be Tencent QQ™ client (referred as “QQ client” hereafter), Weibo (which is one type of Twitter) client, a web browser, etc. The first-party server can be a server-side application corresponding to the client-side application, and it can be, for example, a QQ server, a Weibo server, etc. The third-party server can be a corresponding third-party website, such as a shopping site, an email website, a web forum site, etc.

Furthermore, in some embodiments, acquiring from first-party server 102 the authorization information for logging in to third-party server 103 may include the following steps:

Mobile terminal 101 receives, via a web browser, the login request message submitted by the user to third-party server 103. After receiving the login request message, third-party server 103 transmits to mobile terminal 101 login page information, which includes at least one account system login link. A user can then click on the at least one account system login link to log into the account system.

Mobile terminal 101 receives and displays, via its browser, the login page information. And mobile terminal 101 then detects or determines that the user has clicked on any one of the at least one account system login link on the login page, and that the mobile terminal browser supports cross-site login (e.g. the browser has installed components for cross-site login, which is a cross-domain or cross-site single sign-on mechanism through which a user can use one set of login credentials, such as a QQ account number/password, to gain access to multiple secured websites or systems). Afterwards, mobile terminal 101 acquires, from first-party server 102 that is associated with the clicked login link, the authorization information for logging onto third-party server 103.

Furthermore, in some embodiments, exemplary system 100 may also include a second-party server 104. Second-party server 104 connects and communicates with mobile terminal 101, first-party server 102, and third-party server 103 via a data network. Second-party server 104 can be used to manage first-party server 102, or a third-party server authorized by first-party server 102. Exemplary embodiments are described as follows:

Mobile terminal 101 acquires from first-party server 102 its login status information of an account that has logged into an account system (referred as “logged-in account” hereafter), and transmits to second-party server 104 the login status information and/or the authorization information. Second-party server 104 verifies the login status information and/or the authorization information (in some embodiments, second-party server 104 may pre-store the login status information and/or the authorization information of the first-party server 102). After having passed the verification, second-party server 104 transmits to the mobile terminal 101 authorization page information, prompting the user to confirm authorizing third-party server 103 to use the logged-in account information to log in the third-party server.

Mobile terminal 101 receives and displays the authorization page information. After receiving the user's confirmed authorization, mobile terminal 101 transmits the confirmation to second-party server 104.

After receiving the confirmed authorization, second-party server 104 transmits an user identifier (“OpenID”) and an authorization token (“Token”) to third-party server 103. After receiving the user identifier and the authorization token, third-party server 103 transmits to second-party server 104 a request message for acquiring the logged-in account information. The request message carries the user identifier and the authorization token.

After receiving the request message, second-party server 104 verifies the user identifier and the authorization token. After having passed the verification, second-party server 104 then transmits the logged-in account information to third-party server 103.

In some embodiments, the login status information can be encrypted and transmitted in a predetermined format. In some embodiments, the login status information comprises a timestamp, indicating that the login status information is valid within a certain time frame (e.g. within 1 minute after the timestamp). In some embodiments, in order to enhance security, the login status information can be associated with an application identifier (e.g., AppID) included in the authorization information. The login status information is valid for a specific application identifier.

Furthermore, in some embodiments, after receiving the logged-in account information transmitted from the second-party server, the third-party server authorizes a mobile terminal user to log in using the logged-in account.

FIG. 2 illustrates an exemplary application for controlling mobile terminal access to third-party resources according to embodiments of the present disclosure. The exemplary application involves several components or players, for example, a mobile terminal user 220, a web application WebApp 222, a cross-site login page such as a QQ login page 224, a mobile terminal browser 226, a client-side application such as a mobile terminal QQ 228, and a cross-site login server such as a QQ cross-site login server 230. In some embodiments, WebApp 222, QQ login page 224, mobile terminal browser 226, and mobile terminal QQ may be running on a mobile terminal 101 of FIG. 1. The above components interact with each other to control mobile terminal access to third-party resources, as described below.

At step S201, mobile terminal user 220 browses or opens WebApp 222 via, for example, a mobile terminal browser 226. The browser is installed with a QQ cross-site-login component. At step S202, WebApp displays a login page and prompts the user to login. In some embodiments, the login page includes a QQ login link to support the user to conduct cross-site login with the user's QQ account. At step S203, upon detecting that the user has clicked on the QQ login link, a QQ login page 224 is displayed. At step S204, the QQ login page inquires whether mobile terminal browser 226 supports QQ cross-site login.

At step S205, if the mobile terminal browser supports QQ cross-site login, QQ login page 224 transmits to mobile terminal browser 226 parameters needed to log in to the user's QQ account. The parameters includes an application identifier AppID (which is an identifier assigned by a QQ cross-site-login component when a third-party application uses a QQ account for cross-site login), a scope of required authorization, redirect_URL for website redirection, and other parameters. In some embodiments, to enhance security, the parameters can be encrypted. If the mobile terminal browser does not support QQ cross-site login, it may prompt the user to enter a login name and a password.

At step S206, after acquiring the parameters for QQ login, mobile terminal browser 226 can open, run, or activate a client-side application such as a mobile terminal QQ 228 through the QQ cross-site-login component. The browser then transmits the parameters to the mobile terminal QQ. In some embodiments, if the mobile terminal QQ is not installed on the mobile terminal, the mobile terminal QQ would fail to run, and the mobile terminal browser may display error information on the QQ login page, which prompts the user to enter a login name and a password to login.

At step S207, after being activated, mobile terminal QQ 228 prompts the user to login if the user has not logged in. If the user has logged into mobile terminal QQ 228, the mobile terminal QQ decrypts and verifies the parameters transmitted by mobile terminal browser 226.

At step 208, after having passed the verification of the parameters, mobile terminal QQ 228 returns login status information to mobile terminal browser 226. In some embodiments, the login status information is encrypted and transmitted in a predetermined format. The login status information may comprise a timestamp, indicating that the login status information is valid within a certain time frame (e.g. within 1 minute after the timestamp). In some embodiments, in order to enhance security, the login status information can be associated with an application identifier in authorization information. That means that the login status information is valid for a specific AppID. Moreover, although not shown in FIG. 2, mobile terminal QQ 228 can also synchronize the login status information with that stored on a QQ cross-site login server 230. The synchronized login status information can be used by the cross-site login server for subsequent verification of the login status information.

At step S209, after acquiring the login status information from mobile terminal QQ 228, mobile terminal browser 226 sends or transmits the login status information to QQ login page 224. At step S210, QQ login page 224 sends or transmits the login status information and the parameters for QQ login to QQ cross-site login server 230 for verification. At step S211, after having passed the verification, QQ cross-site login server 230 displays an authorization page to mobile terminal user 220, prompting the user to confirm authorizing WebApp 222 to use the QQ account information (including a nickname, a head portrait, etc.) for cross-site login.

At step S212, after receiving the user's confirmation authorizing the use of the QQ account information for cross-site login, QQ cross-site login server 230 sends to WebApp 222 a user identifier (“OpenID”) and a authorization token (“Token”). An OpenID servers as the user's unique identifier after the user has logged in a WebApp. Each OpenID is uniquely associated with a QQ number (which is a QQ account number), while each QQ number can be associated with different OpenIDs in different WebApps. Also, a Token can be provided by a QQ server after the mobile terminal user authorizes using his/her QQ number to log in a WebApp. The Token is a character string that the QQ server provides to the WebApp to indicate that the user's authorization is valid.

At step S213, according to the OpenID and Token, WebApp 222 sends to QQ cross-site login server 230 a request for the user's QQ account information such as a nickname, a head portrait, etc. The request includes the OpenID and Token. At step S214, after confirming that the received OpenID and Token are valid, QQ cross-site login server 230 returns the requested nickname, head portrait, and other information to the WebApp.

At Step S215, after acquiring the nickname, head portrait, and other information, WebApp 222 authorizes the user to log in the WebApp using the acquired information, displays to the user the logged-in page information, and completes the login and authorization process.

In this exemplary application, QQ cross-site login server 230 can represent a first-party server 102 of this disclosure while QQ login page 224 is a client-side application associated with the first-party server. A QQ server (not shown in FIG. 2) for mobile terminal QQ 228 or mobile terminal QQ 228 can represent a second-party server 104 of this disclosure. And a server proving services for WebApp 222 can represent a third-party server 103 of this disclosure.

This exemplary application demonstrates that a mobile terminal user can access, via an existing QQ account, all mutually-trusted third-party applications, without registering additional login accounts. This simplifies the user's login process and improves user's access efficiency.

It is appreciated by an ordinary skill in the art that this exemplary application is provided for an explanatory purpose, but not for limiting the scope of this disclosure.

Based on the system architecture as shown in FIG. 1, embodiments of the present disclosure provide an exemplary interactive method for controlling mobile terminal access to third-party resources. As shown in FIG. 3, embodiments of the interactive method are described as follows.

At step S301, through a client-side application associated with an account system, a user of mobile terminal 101 logs in a first-party server 102 that corresponds to the client-side application. Afterwards, based on the user's operation command, the mobile terminal acquires from the first-party server authorization information to be used for logging onto a third-party server 103. The authorization information includes a logged-in account.

In some embodiments, step S301 further includes the following steps: Mobile terminal 101 receives, via its browser, login request information sent by the user to third-party server 103. After receiving the login request information, the third-party server sends login page information to the mobile terminal. In some embodiments, the login page information includes at least one account system login link.

The mobile terminal receives and displays, via its browser, the login page information. And the mobile terminal then detects and determines that the user has clicked on any of the at least one login link included in the login page information, and that the mobile terminal browser supports cross-site login. Based on a detection result, the mobile terminal acquires, from a first-party server corresponding to the clicked login link, authorization information using which the user can log onto the third party server.

In some embodiments, the authorization information includes, but is not limited to, an application identifier AppID, a scope of authorization (e.g. what the user can do after logging onto the third-party server), redirect_URL for webpage redirection, and other information. In some embodiments, the client-side application associated with an account system can be, for example, a QQ client, a Weibo client, etc. The first-party server can be a server-side application corresponding to the client-side application, and it can be, for example, a QQ server, a Weibo server, etc. The third-party server can be a corresponding third-party site, such as a shopping site, an E-mail website, a web forum site, etc.

Referring back to FIG. 3, at step S302, mobile terminal 101 transmits to third-party server 103 login request information that carries the authorization information. In some embodiments, the authorization information may be encrypted. The mobile terminal includes the encrypted authorization information into the login request information, and transmits it to third-party server 103.

At step S303, after receiving the login request information, third-party server 103 verifies the authorization information included in the login request information, and authorizes the mobile terminal user to log in using the logged-in account included in the authorization information after the verification is successful. In some embodiments, if the authorization information is encrypted, the verification can occur after the decryption. In some embodiments, the verification can be focused on an AppID, a scope of authorization, etc.

Furthermore, in some embodiments, the exemplary method may also include the following steps:

The mobile terminal acquires, from the first-party server, the login status information of the logged-in account, and sends the login status information and/or authorization information to the second-party server. The second-party server verifies the login status information and/or the authorization information. After passing the verification, the second-party server sends authorization page information to the mobile terminal, prompting the user to confirm authorizing the third-party server to use the logged-in account information for cross-site login.

The mobile terminal receives and displays the authorization page information and, after receiving the confirmation from the user, sends the confirmation to the second-party server. After receiving the confirmation, the second-party server sends the user's OpenID and Token to the third-party server. After receiving the OpenID and Token, the third-party server sends to the second-party server a request information for acquiring logged-in account information. The request information includes the OpenID and the Token. After receiving the request, the second-party server verifies the OpenID and Token in the request and, after verification, sends the logged-in account information to the third-party server.

In some embodiments, the login status information is encrypted and sent in a predetermined format. In exemplary embodiments, the login status information also includes a timestamp, indicating that the login status information is valid within a certain time frame (e.g. within 1 minute after the timestamp). In some embodiments, in order to enhance security, the login status information can be associated with an AppID included in the authorization information. In some embodiments, the login status information is valid for a specific AppID.

In some embodiments, after receiving the logged-in account information sent by the second-party server, the third-party server authorizes the mobile terminal user to log in using the login name of the logged-in account information.

In exemplary embodiments of the present disclosure, the mobile terminal user can access all mutually-trusted third-party servers, using a login name of an existing account system. In this way, there is no need for the mobile terminal user to register different accounts for different websites, nor to memorize the account information for different websites, nor to repeatedly enter different account information for validation and login to different websites. As a result, it simplifies the user's operation process, and improves access efficiencies. Furthermore, the risk of leaking account information due to repeated entering account numbers and passwords can be avoided, and the access security can be enhanced.

Based on the system architecture diagram shown in FIG. 1, embodiments of the present disclosure also provides a method for controlling mobile terminal access to the third-party server, as shown in FIG. 4. The exemplary method can be implemented by mobile terminal 101 as shown in FIG. 1. The exemplary method is described as follows.

At step S401, a user logs in a first-party server that corresponds to the client-side application, through a client-side application associated with an account system. Afterwards, based on the user's operation command, mobile terminal 101 acquires from the first-party server authorization information to be used for logging into the third-party server. The authorization information includes a logged-in account.

At step S402, the mobile terminal transmits to the third-party server login request information that carries the authorization information. After receiving the login request information, the third-party server can verify the authorization information included in the login request information, and after the verification, authorize the mobile terminal user to log in the server using the logged-in account included in the authorization information.

In some embodiments, the mobile terminal's acquisition of the authorization information based on the user's operation command further includes the following steps:

The mobile terminal receives, via its browser, the login request information sent by the user to the third-party server, so that the third-party server can send login page information to the mobile terminal after receiving the login request information. The login page information can include at least one account system login link.

The mobile terminal receives and displays, via its browser, the login page information. After detecting that the user clicks on the at least one account system login link, and that the mobile terminal browser supports cross-site login, the mobile terminal acquires, from the first-party server that corresponds to the clicked link, authorization information to be used for logging in to the third-party server.

Furthermore, the exemplary embodiments also include the following steps: The mobile terminal acquires, from the first-party server, login status information for the logged-in account, and sends the login status information and/or authorization information to the second-party server. The second-party server verifies the login status information and/or authorization information. After the verification, the second-party server transmits authorization page information to the mobile terminal prompting the user to confirm authorizing the third-party server to use the logged-in account information to log in. The mobile terminal receives and displays the authorization page information and, after receiving the user's confirmation for the authorization, sends the confirmation to the second-party server. After receiving the confirmation, the second-party server sends a user identifier (“OpenID”) and an authorization token (“Token”) to the third-party server.

In the exemplary embodiments, the login status information comprises a timestamp. And the login status information is associated with an application identifier AppID.
